           Summary: MessagePort must set m_closed to be true at the end of
                    MessagePort::close function
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: li.yin at intel.com


In the function MessagePort::close, the "m_closed = true" must be executed at the end of function, not at the beginning.
Or, the m_entangledChannel->close() will not be executed.
And it resulted in the failure of MS bench mark messagechannel_close.htm.
You can try it from http://samples.msdn.microsoft.com/ietestcenter/WebWorkers/messagechannel_close.htm
